WI-IIFFLETREE.

Specification of Letters Patent No. 15,460, dated July 29, 1856.

To all whom t may concern.'

Be it known that I, GEORGE KENNY, of Milford, in the county of Hillsboroand State of New Hampshire, have invented certain new and usefulImprovements in IVhiliietrees, and that the following description, takenin connection with the accompanying drawings, hereinafter referred to,

forms a full and exact specification of the same, wherein I have setforth the nat-ure and principles of my said improvements, by which myinvention may be distinguished from others of a similar class, togetherwith such parts as I claim and desire to have secured to me by LettersPatent.

rIhe figures of the accompanying plate of drawings represent myimprovements.

Figure l, is a longitudinal central vertical section of a whiffle-treewith my improvements applied thereto. V`F ig. 2 is a transverse verticalsection of the same taken in the plane of the line A B, Fig. l.

Vhiffle-trees, as commonly constructed and applied, have been foundobjectionable on account of the rattling noise produced by them, andtheir liability to wear out quickly by turning on the king-bolt. Thepresent invention obviates these objections as by my improvements rubberis applied to the parts that play upon the king bolt7 and in such amanner as to prevent the entrance of dirt &c., which otherwise wouldprevent the accomplishment of the desired results.

a a in the drawings represent the whiffletree and ZJ b the draw-bar.

c c is the king-bolt or pin that con nects the whiffletree and draw-bar.

This bolt c c is held stationary in the drawbar.

Attached to the under part of the whifIie'- l tree is a metallic platecl Z having a circular flange e e which tops over and plays upon theflanges j', f, forming a part of a plate g g, similar to the plate z 7Lfastened to the upper side of the draw-bar Z2 b. In the box thus formedby the flanges e e f f, a piece of vulcanized rubber i is insertedaround the bolt c c. The head of the boltl c c is protected in a similarmanner, by means of a box cap 7c, attached to the brace j, which fitsover and plays upon the circular iange l Z of a plate m m secured to theupper side of the whiffle-tree. In the box L u is inserted a piece ofrubber fn, fitting around the cking-bolt c c. By this arrangement itwill be seen that the parts which are exposed to wear by the ordinarymethod of constructing and applying whiffle-trees are completelyprotected by the use of the rubber, which is kept free from the entranceof dirt- &c., by the peculiar manner in which it is applied, that is bybeing inserted in boxes which cover and inclose the rubber. Thus allnoise and liability to wear are effectually prevented.

I-Iaving thus described my improvements I shall state my claim asfollows What I claim as my invention and desire to have secured to me byLetters Patent 1s- The combination of rubber washers with the whiflietrees and about the king bolt and the boxes arranged with the samesubstantially as described, so as to protect the rubber and boxes fromthe entrance of water dirt &c. and thereby preventing the wear of theparts.
